Let's divide 139281 by 87
Let's see how many times 87 fits into 139281.

On to step 1:
1 divided by 87 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 87

Moving on to step 2:
If we divide 13 by 87, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 87

Step 3:
The number 87 fits into 139 1 times, leaving a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 87 from 139 and we're left with 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 87

Going ahead to step 4:
When dividing 522 by 87, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 0 after subtracting 522 from 522.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 87

Moving on to step 5:
87 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 87

Going ahead to step 6:
87 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 1600.0
The remainder is 81 after subtracting 0 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
When dividing 810 by 87, we get 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1600.9
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
When dividing 270 by 87, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 1600.93
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
90 divided by 87 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1600.931
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
If we divide 30 by 87, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 1600.931
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
If we divide 300 by 87, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 1600.93103
Subtract 261 from 300 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 12:
87 goes into 390 4 times with a remainder of 42.
The next digit of our result is 4. 
Result so far: 1600.931034
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
When dividing 420 by 87, we get 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 1600.9310344
Subtract 348 from 420 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 1600.9310344 with a balance of 7.2e-07.
